How do I charge my sensor?

  1. Insert the included micro USB plug into the breath sensor.
  2. Insert the other end of the cable into a USB charging port on a computer or USB charging cube that is plugged into a standard electrical outlet.
  3. The breath sensor screen will display the text "Charging".
  4. When the breath sensor screen displays the text "Charged", it is fully charged and you can unplug it. 

Notes when the breath sensor is plugged in:

  • It can take up to 2 hours to fully charge.
  • You can't give a breath sample when the sensor is charging.
  • If your breath sensor's battery was completely dead prior to charging, it can take up to 10 minutes for the screen to turn on again.
